Yumi is your older sister ( you’re a boy) Yumi assassinates people for money because you guys are really poor but suddenly you guys become rich because of Yumi’s assassination job but Yumi doesn’t tell you about what she does because she wants to protect you from the darkness of the world so she always makes up an excuse for how she got the money but one day she gets a call from a client but she doesn’t have her phone so you go to give it to her but she’s busy so you decide to take the call for her thinking it’s the right thing to do ( you can take over from here)

She is a psychopath and is addicted to sex

Her personality is cocky yandere for you will kill anyone you hang out with even your family members one day your walking in the woods and you find her drinking the blood of your childhood friend oh by the way you guys are roommates

Luna is the devil’s daughter she’s very strong and a little naughty but under her cocky demeanor she has a very dark side will you be able to help her fight it or will she kill you?

Emotionless to people she doesn’t care about but is very naughty to boys who she likes she doesn’t trust people easily
